[0020] In existing technologies, batteries and circuit boards are usually made into a non-removable whole. When users no longer use the whole device with the battery, these devices are often discarded because the battery is difficult to remove or the removal process is extremely cumbersome, leading to a series of problems such as environmental pollution and water pollution.

[0021] Alternatively, even if the battery and circuit board are removable, the complex connection structure often requires specific tools or equipment for disassembly and installation, increasing the difficulty and time cost for users. Furthermore, some battery installation methods may damage the battery during disassembly, further increasing the cost of battery replacement.

[0022] Therefore, this utility model provides a battery pack module that is easy to assemble and disassemble, so that users can easily disassemble and replace the battery body and / or circuit board.

[0023] Please see Figure 1 The battery pack module includes a mounting frame 1, a battery body 2, and a circuit board 3. The mounting frame 1 is a frame structure composed of multiple crossbeams and longitudinal beams connected at intersections, forming multiple spaces for mounting and securing components such as the battery body 2 and the circuit board 3. The battery body 2 is fixedly mounted on the first side of the mounting frame 1, and the circuit board 3 is detachably connected to the second side of the mounting frame 1. The second side of the mounting frame 1 faces away from the battery body 2; that is, the first and second sides of the mounting frame 1 are opposite to each other. The battery body 2 can be mounted on the mounting frame 1 by adhesive, screw fixing, or snap-fit ​​connection, ensuring that the battery body 2 is stable and does not wobble on the mounting frame 1. The circuit board 3 can be detachably connected to the mounting frame 1 by threaded fasteners, snap-fit ​​connection, etc., to facilitate the removal and installation of the circuit board 3. The battery body 2 can be a lithium battery, lead-acid battery, or other types of battery. The circuit board 3 is used for charging and discharging control of the battery body 2, or for converting the electrical energy provided by the battery body 2 into the voltage and current required by the device.

[0024] The battery pack module also includes a wire 4, which connects the battery body 2 and the circuit board 3 to transmit electrical energy from the battery body 2 to the circuit board 3. The first end 41 of the wire 4 is fixedly connected to the battery body 2, for example, by soldering the first end 41 to the battery body 2. The second end 42 of the wire 4 extends to the side of the circuit board 3 opposite to the battery body 2 and forms an electrical connection with the circuit board 3. It should be noted that the connection between the second end 42 of the wire 4 and the circuit board 3 is not soldered, but achieved through crimping. Since the battery body 2 and the circuit board 3 are located on opposite sides of the mounting bracket 1, the two ends of the wire 4 should also be correspondingly located on opposite sides of the mounting bracket 1; specifically, the wire 4 may or may not pass through the mounting bracket 1. If the wire 4 passes through the mounting bracket 1, the mounting bracket 1 simply needs to have corresponding wire holes.

[0025] To achieve crimping of the second end 42 of the wire 4, the battery pack module also includes a rotating snap-fit ​​component 5. Specifically, please refer to... Figure 2The rotating snap-fit ​​component 5 includes a rotating body 51, a sleeve portion 52, and a snap-fit ​​portion 53. The rotating body 51 can be of any shape, as long as it can cover the second end 42 of the wire 4. Figure 5 Only a plate-like structure is shown. This plate-like structure is simple and can cover the second end 42 of the wire 4. The sleeve part 52 and the snap-fit ​​part 53 are respectively connected to the rotating body 51. The relative positions of the sleeve part 52 and the snap-fit ​​part 53 on the rotating body 51 are not limited. For example, they can be set close to each other or far apart. They can be located on the same edge of the rotating body 51 or on different edges. As long as the sleeve part 52 and the snap-fit ​​part 53 are spaced apart from each other, their respective functions can be realized.

[0026] Please see Figure 2 and Figure 3 Correspondingly, the mounting bracket 1 has a fixed shaft 11 and a slot 12, so that the sleeve part 52 is sleeved on the fixed shaft 11 and can rotate around the fixed shaft 11. The positions of the fixed shaft 11 and the slot 12 are not specifically limited, as long as they correspond to the sleeve part 52 and the snap-fit ​​part 53 respectively. The cross-section of the fixed shaft 11 can be triangular, polygonal, or circular, etc., with a circle being the preferred option, allowing the sleeve part 52 to rotate smoothly around the fixed shaft 11. The fixed shaft 11 can be a cantilever beam structure connected at one end, or a stable beam structure connected at both ends (e.g., Figure 3 (As shown). The specific shape of the slot 12 is not limited in this utility model. For example, it can be a through hole or a groove, as long as it can be engaged by the engaging part 53.

[0027] The sleeve portion 52 and the snap-fit ​​portion 53 can each be one or multiple. Correspondingly, one or more fixed shafts 11 and snap-fit ​​slots 12 can also be provided. However, when multiple fixed shafts 11 are provided, the axes of these fixed shafts 11 must be located on the same straight line to ensure the formation of an effective rotation axis. Providing multiple snap-fit ​​slots 12 and snap-fit ​​portions 53 can enhance the stability of the snap-fit, but this increases the complexity of operation. Figure 2 and Figure 3 For example, it only shows the case where there is only one sleeve part 52, one snap-fit ​​part 53, one fixed shaft 11 and one slot 12. It is easy to operate and can realize rotation and snap-fit ​​functions.

[0028] Please see Figure 4 and Figure 5 During the rotation of the sleeve part 52, the locking part 53 has at least two states: a first state in which it is locked in the slot 12 (e.g., ...). Figure 5 (as shown) and the second state of being disengaged from the card slot 12 (as shown) Figure 4(As shown). In the first state, the second end 42 of the wire 4 is pressed between the rotating body 51 and the circuit board 3. In the second state, the rotating body 51 is removed from the circuit board 3, and the second end 42 of the wire 4 can be removed from the circuit board 3. When the user wants to disassemble the battery body 2, he only needs to operate the locking part 53 of the rotating locking member 5 to switch it from the first state to the second state of being disengaged from the slot 12. At this time, the rotating body 51 will be removed from the circuit board 3, and the second end 42 of the wire 4 will also be removed from the circuit board 3. The electrical connection between the battery body 2 and the circuit board 3 will be disconnected, and the user can then disassemble the circuit board 3 and the battery body 2. Conversely, when the user wants to assemble the battery pack module, first, the battery body and the circuit board 3 are installed on both sides of the mounting bracket 1, and then the second end 42 of the wire 4 on the battery body 2 is pulled to the circuit board 3; then, the sleeve part 52 of the rotating locking member 5 is sleeved on the fixed shaft 11, and the rotating body 51 is rotated to switch the locking part 53 from the second state to the first state of being engaged in the slot 12. At this time, the second end 42 of the wire 4 will be pressed between the rotating body 51 and the circuit board 3, thereby establishing an electrical connection between the battery body 2 and the circuit board 3, and completing the assembly of the battery pack module.

[0029] It is understandable that ensuring the continuity and disconnection of the circuit between the circuit board 3 and the battery body 2 is a crucial step in the assembly and disassembly of the battery pack module; that is, the installation and removal of the second end 42 of the wire 4 is also a critical step. By providing the rotating snap-fit ​​connector 5, the second end 42 of the wire 4 can be easily removed from the circuit board 3, thus disconnecting the circuit between the circuit board 3 and the battery body 2; similarly, the second end 42 of the wire 4 can also be easily reconnected to the circuit board 3, thereby restoring the circuit continuity between the circuit board 3 and the battery body 2. No additional tools are required in this process. Therefore, the introduction of the rotating snap-fit ​​connector 5 greatly simplifies the assembly and disassembly process of the battery pack module, making it exceptionally convenient.

[0030] The battery pack module provided by this utility model includes a mounting frame 1, a battery body 2, a circuit board 3, wires 4, and a rotating snap-fit ​​component 5. The mounting frame 1 is provided with a fixed shaft 11 and a slot 12 spaced apart; the battery body 2 is disposed on a first side of the mounting frame 1; the circuit board 3 is disposed on a second side of the mounting frame 1 away from the battery body 2; the first end 41 of the wire 4 is fixedly connected to the battery body 2, and the second end 42 of the wire 4 extends to the side of the circuit board 3 away from the battery body 2; the rotating snap-fit ​​component 5 includes a rotating body 51 and a sleeve portion 52 and a snap-fit ​​portion 53 respectively connected to the rotating body 51; the sleeve portion 52 is sleeved on the fixed shaft 11 and can rotate around the fixed shaft 11; wherein, during the rotation of the sleeve portion 52, the snap-fit ​​portion 53 has a first state of being snapped into the slot 12 and a second state of being disengaged from the slot 12; in the first state, the second end 42 of the wire 4 is pressed between the rotating body 51 and the circuit board 3; in the second state, the rotating body 51 is removed from the circuit board 3, so that the second end 42 of the wire 4 can be removed from the circuit board 3. This invention simplifies the assembly process by placing the battery and circuit board 3 on opposite sides of a mounting bracket 1, and ensuring a circuit connection between them via a wire 4. The mounting bracket 1 is equipped with a fixed shaft 11 and a slot 12 for easy installation of the rotating snap-fit ​​connector 5. When the battery needs to be replaced, the second end 42 of the wire 4 can be easily detached from the circuit board 3 by operating the rotating snap-fit ​​connector 5. During assembly, the battery and circuit board 3 are first installed, and then the second end 42 of the wire 4 is securely pressed onto the circuit board 3 using the rotating snap-fit ​​connector 5. Therefore, this battery pack module not only simplifies the assembly and disassembly process but also effectively reduces operational complexity and time costs.

[0031] In some embodiments, please refer to Figure 6 In order to achieve stable pressing of the rotating body 51 onto the second end 42 of the wire 4, the relative positions of the sleeve portion 52 and the snap-fit ​​portion 53, as well as their extending directions, are defined. Specifically, the rotating body 51 is positioned in its width direction (this width direction is...) Figure 6 (represented by dashed line a) has a first edge 511 and a second edge 512 opposite to each other; a sleeve portion 52 is connected to the first edge 511, and a snap-fit ​​portion 53 is connected to the second edge 512; wherein, in the first state, both the sleeve portion 52 and the snap-fit ​​portion 53 extend toward the direction of the battery body 2, as shown in the figure. Figure 5 As shown, circuit board 3 is wrapped around it.

[0032] Thus, in the first state, the sleeve portion 52 is sleeved on the fixed shaft 11, and the snap-fit ​​portion 53 is snapped into the slot 12. The rotating body 51, the sleeve portion 52, and the snap-fit ​​portion 53 together form a ring-shaped structure that encircles a portion of the circuit board 3. Since the sleeve portion 52 and the snap-fit ​​portion 53 are respectively connected to opposite sides of the rotating body 51, namely the first edge 511 and the second edge 512, the rotating body 51 can provide a more balanced support force when encircling the circuit board 3, preventing the circuit board 3 from tilting or shaking under force.

[0033] Furthermore, this encircling structure can effectively prevent external factors (such as vibration and impact) from affecting the circuit connection between the circuit board 3 and the battery body 2. When the battery pack module is subjected to external vibration or impact, the encircling structure can absorb some of the energy, reduce the relative displacement between the circuit board 3 and the battery body 2, thereby protecting the circuit connection from damage.

[0034] The sleeve portion 52 and the snap-fit ​​portion 53 can be arranged facing each other directly or at an angle (e.g., ...). Figure 6 (As shown). It can be understood that when the parts are arranged at an angle, the sleeve portion 52 and the snap-fit ​​portion 53 are farther apart, which can reduce the phenomenon of uneven force on the rotating body 51 in the first state. When the parts are arranged face-to-face, the sleeve portion 52 and the snap-fit ​​portion 53 are closer together. Therefore, in the first state, the rotating snap-fit ​​member 5 may be unstable due to the close relative positions of the sleeve portion 52 and the snap-fit ​​portion 53.

[0035] In some embodiments, please continue reading Figure 6 To further enhance the stability of the encircling structure, the rotating latching member 5 also includes an extension 54. Specifically, the extension 54 connects to the second edge 512, and the extension 54 is spaced apart from the latching part 53. In the width direction of the rotating body 51, the extension 54 and the sleeve part 52 are directly opposite each other, and the latching part 53 and the sleeve part 52 are diagonally opposite each other. This makes the extension 54, the sleeve part 52, and the latching part 53 roughly evenly distributed around the periphery of the rotating body 51. Furthermore, in the first state, the extension 54 also extends towards the battery to encircle the circuit board 3. Thus, the distributed layout of the extension 54, the sleeve part 52, and the latching part 53 also enables the rotating latching member 5 to more effectively disperse and resist external forces when subjected to stress, thereby improving the overall vibration and impact resistance of the battery pack module.

[0036] In some embodiments, please refer to Figure 4 and Figure 6To ensure the second end 42 of the wire 4 is more firmly clamped under the action of the rotating body 51, the second end 42 of the wire 4 is positioned close to the sleeve portion 52 and the extension portion 54, and located in the central region of the sleeve portion 52 and the extension portion 54. Therefore, when the rotating body 51 rotates to the first state, the sleeve portion 52 and the extension portion 54 can respectively clamp the circuit board 3 near the second end 42 of the wire 4, thereby enhancing the clamping firmness of the second end 42 of the wire 4. Furthermore, since the second end 42 of the wire 4 is located in the central region of the sleeve portion 52 and the extension portion 54, this arrangement helps reduce the risk of the wire 4 shaking or falling off under force, further improving the stability of the battery pack module circuit connection.

[0037] In some embodiments, please refer to Figure 5 and Figure 6 To quickly achieve engagement and disengagement between the engaging portion 53 and the slot 12, a pressing end 5311 is formed. Specifically, the engaging portion 53 includes a first elastic arm 531 and a latch 532. The first elastic arm 531 is connected to the second edge 512 of the rotating body 51 and extends in a meandering manner away from the rotating body 51 to form the pressing end 5311. Here, "meandering extension" refers to extending in a tortuous or curved manner; therefore, the first elastic arm 531 forms one or more continuous U-shaped or V-shaped structures in this way; the U-shaped or V-shaped structure furthest from the rotating body 51 can be considered as the pressing end 5311. For example, Figure 6 The first elastic arm 531 forms a U-shaped structure, which is simple in structure and can realize the pressing function.

[0038] Furthermore, the latch 532 is disposed on the pressing end 5311 of the first elastic arm 531 and on the side opposite to the rotating body 51; wherein, the pressing end 5311 of the first elastic arm 531 can move toward or away from the rotating body 51, so that the latch 532 switches between the state of engaging the slot 12 and disengaging from the slot 12.

[0039] Thus, the user can switch the latch 532 between engaging and disengaging from the slot 12 by pressing the pressing end 5311 of the first elastic arm 531. Specifically, when disassembling the battery pack module, the user only needs to apply a certain pressure to the pressing end 5311 to cause the first elastic arm 531 to elastically deform, thereby causing the latch 532 to disengage from the slot 12. At this time, the rotating latch 5 can switch from the first state to the second state, and the user can easily separate the battery body 2 and the circuit board 3. Conversely, when assembling the battery pack module, the user only needs to place the sleeve part 52 of the rotating latch 5 onto the fixed shaft 11, and align the latch 532 with the slot 12 through the guide structure. Then, the pressure on the pressing end 5311 is released, and the first elastic arm 531, under the action of elastic restoring force, causes the latch 532 to engage with the slot 12, completing the installation of the rotating latch 5. At this time, the rotating latch 5 is in the first state, which can be combined with Figure 4 Understanding this, the second end 42 of the wire 4 is crimped between the rotating body 51 and the circuit board 3, thus establishing a circuit connection between the battery body 2 and the circuit board 3. This method not only simplifies the assembly and disassembly process of the battery pack module but also improves the accuracy and efficiency of assembly and disassembly.

[0040] In some embodiments, please continue reading Figure 5 and Figure 6 To facilitate pressing the pressing end 5311, the tail end of the pressing end 5311 is extended. Specifically, in the first state, the tail end of the pressing end 5311 of the first elastic arm 531 extends out of the mounting bracket 1. The tail end of the pressing end 5311 can extend out of the mounting bracket 1 in any direction. For example, the tail end of the pressing end 5311 extends approximately upward in the thickness direction of the rotating body 51 (upward refers to the direction above in the standard placement state where the circuit board 3 faces upward and the battery body 2 faces downward).

[0041] In this way, users can more easily press the tail end of the pressing end 5311 to disengage the latch 532 from the slot 12, thus simplifying the disassembly process of the battery pack module. In addition, this design also allows users to more accurately align the latch 532 with the slot 12 when assembling the battery pack module, improving the accuracy and efficiency of assembly.

[0042] In some embodiments, please refer to Figure 6 To reduce stress concentration inside the pressing end 5311, a hollow area 5312 is designed in the pressing end 5311 to disperse stress. These hollow areas 5312 are connected to the root of the latch 532.

[0043] When the user applies pressure to the pressing end 5311, the hollowed-out area 5312 effectively disperses stress, preventing damage to the pressing end 5311 due to stress concentration. Simultaneously, this design also helps improve the elastic deformation capability of the first elastic arm 531, allowing the latch 532 to engage and disengage more smoothly in the slot 12. Furthermore, the hollowed-out area 5312 reduces the weight of the rotating latch 5, making the entire battery pack module lighter, easier to carry, and easier to install.

[0044] In some embodiments, please refer to Figure 3 and Figure 6 To allow the entire rotating snap-fit ​​component 5 to be removed from the mounting bracket 1, the sleeve portion 52 and the fixed shaft 11 are also detachable. Specifically, the sleeve portion 52 includes a second elastic arm 521 and a sleeve 522. The second elastic arm 521 is connected to the first edge 511 of the rotating body 51; the sleeve 522 is connected to the end of the second elastic arm 521 away from the first edge 511; wherein, both ends of the sleeve 522 are open, and the sidewall of the sleeve 522 forms an opening 5221, which extends through both ends of the sleeve 522; the fixed shaft 11 can pass through the opening 5221 to form a detachable sleeve connection with the sleeve 522.

[0045] Since the sleeve 522 is open at both ends and has openings 5221 extending through both ends on its sidewalls, and the second elastic arm 521 has a certain degree of elasticity, the openings 5221 can be opened by the fixed shaft 11. When the fixed shaft 11 is inserted into the sleeve 522, the second elastic arm 521 will return to its original shape, and the openings 5221 will shrink accordingly, thereby ensuring that the sleeve 522 can be securely installed on the fixed shaft 11.

[0046] When it is necessary to completely remove the rotating snap-fit ​​connector 5 from the mounting bracket 1, the user only needs to apply a certain external force to the second elastic arm 521 to cause it to elastically deform, thereby opening the opening 5221. At this time, the fixed shaft 11 can disengage from the sleeve 522, and the rotating snap-fit ​​connector 5 can be completely removed. This design not only facilitates the installation and removal of the rotating snap-fit ​​connector 5, but also helps to improve the maintainability and flexibility of the battery pack module. In addition, through the cooperation of the second elastic arm 521 and the sleeve 522, a stable sleeve connection between the sleeve part 52 and the fixed shaft 11 is achieved, ensuring the stability and reliability of the rotating snap-fit ​​connector 5 during rotation.

[0047] In some embodiments, please continue reading Figure 3 and Figure 6In order to enable the sleeve portion 52 to quickly disengage from the fixed shaft 11, the second elastic arm 521 is inclined. Specifically, the second elastic arm 521 extends at an angle relative to the rotating body 51, and along the extension direction, the second elastic arm 521 gradually moves away from the rotating body 51; the opening 5221 of the sleeve 522 faces the rotating body 51.

[0048] Therefore, by applying force along the inclined direction of the second elastic arm 521 to push the rotating snap-fit ​​5, the sleeve part 52 can be quickly disengaged from the fixed post.

[0049] In some embodiments, please continue reading Figure 3 and Figure 6 To improve the efficiency of installation and disassembly between the sleeve part 52 and the fixed shaft, a guide plate 5222 is provided at the edge of the opening 5221, the inclination direction of which is consistent with the inclination direction of the second elastic arm 521. Therefore, during installation and disassembly, by applying force along the inclination direction of the second elastic arm 521, the fixed shaft 11 will smoothly slide into or out of the opening 5221 along the guide plate 5222. Especially during installation, when the fixed shaft 11 is inside the guide plate 5222, opening the opening 5221 in advance makes it easier to enter the opening 5221.

[0050] In some embodiments, please refer to Figure 3 To further optimize the assembly and disassembly process of the battery pack module, a guide structure can be installed on the mounting bracket 1. This guide structure can be designed as a slide rail, guide groove, or similar form to guide the rotation of the rotating snap-fit ​​component 5 on the mounting bracket 1. Guided by this structure, users can more accurately install the rotating snap-fit ​​component 5 onto the fixed shaft 11 and easily perform rotation operations when needed. This not only improves the accuracy and efficiency of assembly but also helps reduce the risk of damage due to improper operation.

[0051] In some embodiments, please refer to Figure 1 and Figure 4 To achieve a compact structure, the circuit board 3 has a clearance notch 31. In the first state, the latching part 53 extends into the clearance notch 31. The shape and size of the clearance notch 31 match the latching part 53, allowing the latching part 53 to be inserted into it.

[0052] Meanwhile, the clearance notch 31 also serves to limit the engagement portion 31. In the first state, the engagement portion 53 extends into the limiting notch 31 and, through contact with the sidewall of the limiting notch 31, achieves horizontal limitation of the engagement portion 53 (the horizontal direction is parallel to the board surface direction of the circuit board). This design not only improves the stability of the engagement portion 53 on the circuit board 3, but also helps to ensure the overall reliability and safety of the battery pack module.

[0053] In some embodiments, please refer to Figure 4 and Figure 5 The battery pack module also includes a pull strap 6, which is connected to the outside of the second end 42 of the wire 4 and extends along the extension direction of the wire 4; in the first state, the pull strap 6 is pressed between the rotating body 51 and the second end 42.

[0054] The pull strap 6 not only provides additional fixing force to ensure a secure connection between the second end 42 of the wire 4 and the rotating body 51 and the circuit board 3, but also serves as an operating point during disassembly, facilitating the user's separation of the second end 42 of the wire 4 from the circuit board 3. Specifically, when the user needs to disassemble the battery pack module, they can first press the pressing end 5311 to disengage the latch 532 from the slot 12, and then pull the pull strap 6 to easily remove the second end 42 of the wire 4 from the circuit board 3, further simplifying the disassembly process. During assembly, the user only needs to pull the second end 42 of the wire 4 and the pull strap 6 together to the circuit board 3, and then use the rotating snap-fit ​​5 to press the second end 42 of the wire 4 and the pull strap 6 together between the rotating body 51 and the circuit board 3 to complete the assembly. This design not only improves the convenience of battery pack module assembly and disassembly, but also helps maintain the stability and reliability of the second end 42 of the wire 4 during the connection process.

[0055] In some embodiments, please refer to Figure 1 and Figure 4 To prevent damage to the circuit board 3 from the rotating connector 5, the battery pack module also includes a protective shell 7. The protective shell 7 covers the side of the circuit board 3 facing away from the battery body 2; the protective shell 7 has a clearance hole 71, through which the second end 42 of the wire 4 passes to be electrically connected to the circuit board 3.

[0056] The protective shell 7 effectively prevents the rotating snap-fit ​​component 5 from directly contacting the circuit board 3 during rotation or pressing, thus avoiding damage to the circuit board 3 caused by friction or compression. Simultaneously, the design of the clearance hole 71 in the protective shell 7 ensures that the second end 42 of the wire 4 can pass smoothly and achieve electrical connection with the circuit board 3, while maintaining the coverage of the circuit board 3 by the protective shell 7, improving the safety and reliability of the battery pack module. Furthermore, the introduction of the protective shell 7 enhances the overall structural strength of the battery pack module, enabling it to better resist external vibrations and impacts, further extending the service life of the battery pack module.

[0057] In some embodiments, please refer to Figure 4 To enhance the heat dissipation performance of circuit board 3, a support leg is specially designed on the side of the protective shell 7 closest to circuit board 3 to elevate the protective shell 7. In this way, the heat generated by circuit board 3 can be smoothly dissipated through this elevated space.

[0058] In summary, this utility model, through a series of designs, not only achieves convenient assembly and disassembly of the battery pack module, but also improves its overall structural strength, safety, and reliability. The snap-fit ​​design ensures that the connection between the wires and the circuit board is both secure and easy to separate, greatly simplifying the operation process. Furthermore, optimizations in details such as the guide structure, pressing end, hollowed-out area, and detachable sleeve further enhance the assembly and disassembly efficiency and user experience of the battery pack module. In addition, the introduction of the protective shell not only protects the circuit board from damage but also enhances heat dissipation performance, extending the service life of the battery pack module.

All equivalent package module transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
